To all `whom it may concern.'

, Be it known that I, ROBERT zen ofthe Unitedl States, residing in the village of Oak Park, county of Cook, and

State of Illinois, have invented certain new 'the cotton ljacket,'thus materially adding' to the life of the hose; to provide a construction' in whicha relatively non-elastic fabric ,is so arranged that it `will allow for the" elongation of the lining underpressure and at'the same time preventthe lin-ing from tearin to provide a construction in which the reinforcing fabric is arranged to' allow for ex ansionfof the lining under pressure, but will cause the lining to return to its original flat position when the pressure is removed; to provide aconstruction in which the reinforcing Vfabric prevents the rubber lining from coming into Contact, either when" empty or Vunder pressure, with the rough interior surface of the cot-tont1 jacket, thus causing the bore of the rubber lining toremain smooth and doing away w1th the greatestainou'nt of friction; to Vprovide a construction in which the rubber lining has longitudinal movement independent of the incasin jacket and in which the lining is not un 'er strain when in storage; to provide a construction in which the reinforcement for'therubber lining comprises a plurality of fabric bands, the fabric preferably being wound around the rubber lining and severed to `divide it'into a plurality of independent bands; to so construct and arrange l the reinforcing fabric that the 'free ends of the yarious bands will not register in longitudinal alinement with the ends of the adja-l cent bands; to provide a construction in which there isno rubber cement nor plastic filling used, the lining-not being attached to the cott njacket at any portion of a section of ghe hose, as is the case in the usual MANY, a citi-.-

construction ofhoso of 'this size. Another object of the invention is to reduce the cost of manufacture and in general to provide an improved hose of the character referred to.

the incasing jacket.

In the drawings-i 'Figure 4l'is a crc ss section taken on the line 1-1 of Fig. 2. V i Fig. 2 is a side elevation showing part of Fig. 3 is a side elevation showing the arrangement of the reinforcing Vfabric of the and? designatesthc outer casing or cotton tached from each 0111er.

jacket,` which surro mds `the rubber lining. This outer casing is formed of a woyen fabric, and is construczed` to lie flat when not in use, and my intention contemplates an improved construction of reinforcedrubber lining, which can be detachably employed in combination with a- `iotton jacket.

In previous const ructionsjofhose of this type the rubber lini ug or at least'a portion of it was fix'edly attached to the outer caselastic lining and the relat-irely non-elasticy casing not only interfered with the expansion of the lining, but in case ofvinjury it was impossible Ato re new or repair the parts separately. However, in hose construction embodying my inve ition, the rubber lining is not only `se arate from the cotton jacket, but it is rein Yorced in a manner which will both protect it from rubbing against the rough interior surft ce of the jacket and at the `same time allow ot the necessary expansion and independent movement.

Asshown in Figf). and 3, the reinforcing fabric membel 3 is wound spirally around the rubber lining 1., and at circumferentially disposed portions the member 3 is seyered. This divides the fabric 3 into a plurality of spiral 4mnds having their free ends and 8 adjarent but entirely unatticularly called toj t ie factA that the various n ieet-ing-cdges and 8 are arranged in staggered relation Asoth it there is no longiturlinal portion of the rubber lining that does not have reinforcement in particular Attention is parllO P m of the hose, and at the-same time proyfj wenn.

means for permitting the expansion of the lining as'it fills up.

' In winding the reinforcing fabric member 3 sprally around the lining l1,'there are preferabl 'left intermediate portions 9 of the lining, w ich are not covered by the reinforcin member. This construction, together with t e arrangement for relative movement between thefree ends 7 and4 8, provides for the necessary expansion of the rubber both in a longitudinal and lateral direction. While upon any portion ofthe lining. The fabricmember 3 serves both as a reinforcin member and as a guard for 'holding the lining out of contact with the 'rough interior of-y the. jacket.' However, a lining ,reinforced in this manner will, when emptied, iimnediatelv return to its normal lat position .y within the jacket, and in .folding the hose fon a wagon or packing the. same on rajcks, there 'isp no crease alon the lateral sidesor at the folds..

While I ave shown and described aeparticular arrangement'of parts for reinforcing' the rubber lining, which not secured to 'the cotton jacket, and for returning it,.-when' emp to its normal ilat positlon, it-1s obvit various other constructions could be employed 'within the scope of my invention i 4I for securing the advantages enumerated. By having therubber lining and cotton jacket separate, the lining' is-not under strain when in. storage,'a1 1d it. as at all times independent longitudinal-movement-relative to the 45 cotton jacket, which incases it., Also, while -conveying tu my construction is. particularly applicable for hose of large sizes, such as fire or mill hose, it is not confined to .such use, and I do 'not desire 'to limit the invention except as specified in the appended claims.

I claim as my invention:

1'. In a hose construction, the combination with an inclosingcasinwfor limiting the expansion of an inner lui @nveying tube and for protecting the same, gf-Han inner fluid e adapted slippedinto the casing and held thereinA unattached- .throughout the major portion fof its lengthv and through its circumference, said Vcasing and tube being desi ed when-:out of usa-.to assume a collapsed atte'ned condition fold: ed valong diamet'ritally opposedlengtliwile lines and said tribe having ,ixedly secinl to the outer surfacegthereof spaced apart fabricstrips :for prtcting and reinforcing the" folded edges of p 'e' inner tube. saidstrips 'being spacednpiirt for providing for the expansion of the-tube circumferentizilly,-
